What do you mean with "are you being entertained" ? I do not understand this part.

Imagine, you find one teacher here, and you like her or his style of teaching, and you decide to copy all that that person does and be better than that person. Eventually, you will be a copy of that person and your motivation will be outside of you. You will follow the methods of that person and the criteria of what is a good teacher will be outside of you. Obviously, it is an exaggeration but what I want to say is that happens when you compete when you compare yourself with others and put the criteria of good or bad, outside of you. You lose what you can offer since your originality. 

Competition does not make you better, you will be good at something if you like it if you are truly interested in what you do, that is all.

3. When you have one product, and you like it, and you enjoy it. You are not thinking that it is "the best", simply you enjoy it. The idea of "the best" appears only when you make a comparison if you do not do that it simply does not appear. Think, for example, in your mom or dad, and think about what you like about one of them. If you notice, if you like someone is because you experience pleasure when you are with this person. You are not thinking "I experience more pleasure with my mother than my other mother (because normally we have one)". So there is no such thing how "the best" mother.

4. Yes, autonomy disappears when you compete. It is the same game, Ronaldo - Messi, Nike - Adidas, Microsoft - Apple, etc. You say "Nike will always be Nike", that is not true. Think about Google - Yahoo, when Google was competing with Yahoo, Google was one thing, after Yahoo practically reduce its market's position, Google is another thing. Google, now, is practically the only searcher. And now nobody thinks in terms of "searchers". They say Google directly. Competition makes us think in a certain way so that we think Nike - Adidas, etc. So, the identity of these companies is always changing according to the other company does, because they move according to the market, and what is the market if not a place where you compete! and these companies follow the rules of the market. They are not interested in keeping their own initial values but be competitive and move according to the situation. And when you say "brands will not improve", again, it depends on what is "improve" for you, and you are starting from the premise that companies always give the least and that is not true, there is different kind of companies as there different kind of persons.

1. Yes, I think you will improve as a teacher if you were the only one because you will have more experienced and you will notice what works in every situation or what is better for each student. Now, the question is what is "to improve" for you? Is it to be better than someone else or to do your job more accurately and responsibility?

For example, you can feel that you are "improving" in your way of teaching. But for me, your method of teaching is not valid, and probably for another person, your method of teaching is completely valid. How can you determine if you are improving or not? 

2. In this case, your premise is that all companies only think about their own interest, and they will make or give the least. That not true.

If I am the only one that can solve the problem, so I will do the least effort. ¿Really? I do not think so. I think there is different kind of people and different of companies. I understand your example of internet companies but also there are other companies that act in another way, and they do not need to think about their competition.  

Why do you want to do something good? Normally, people like to do things well. If you are cooking, you want to make a good meal or a delicious dish. Why do you want to be good at your job? Because you want to give a good product or service. Why do you want to be the best at your job? Because you are trapped in ideology. "Competition" is an illusion. "The best" does not exist. Who is the best, Ronaldo or Messi? Well, it depends on the criteria that you have about "The best". Imagine, tomorrow nobody cares about football. Who will be the best footballer? Nobody will care. But, because professional football is a business, we are hearing all the time, "the best is Ronaldo", no! "The best is Messi". Why? Because there is people interested in making money, a lot of money, and they want us to be paying attention to their business. This concept of "Competition", that is very used in economy and business, don't allow us to think why we are doing something, because people are autonomous beings, you do not need to compare yourself to someone else to decide to do something or to take action. When you are acting watching the others, to take them as measuring you, you are losing your autonomy. If you are very good at something, it is because you like what are you doing very much. I know it is difficult to escape this invention of "Competition", the words "Winner" and "Loser", are also inventions. Think, who determines if you are good at or bad at something?
